Transmission Vent Tube AX4N

I seem to have trans fluid belching out of the dipstick tube when it is driven, and wondered if the trans vent could be plugged or something causing it to push fluid out the dip stick? I tried to add some fluid to it and it belched it back out of the tube and funnel on the floor.
Anyone know where it is located?

Thanks,

Below the corrugated intake air snorkel atop the tranny. May remove the black cap and check for plugging with a torch tip cleaner or baling wire. Clean and reinstall 1 click only. If you push it all the way down, you won't have any "venting" action.

Vent cap must be clean, and pushed on the nipple only the first click, then be wobbly loose.

Is the cap that goes on it black? Also, if it is missing, will it still vent?

Thank you all for the quick info. I have only been on this site for a few days and have already learned more about my newly acquired 04 than I thought I would. I sure appreciate it. I hope I can help others out as I continue to learn about this model of car.

Thanks Again.

Looks like the pic black rubber. It lets air in and our but keeps water and dirt out. Alternative is to put a rubber hose on the nipple and run it up and over the brake booster and back down. My used '03 bought 2 years ago had none on it. I got a JY one, no charge. Adding oil or filling it works much better with the cap off. Put oil in the air has to come out. It will either come out the vent or back up the fill tube making it a slow project. Since I loose things and forget things, I would wipe the vent cap off and put it in my pocket. Thus I will not loose it or forget to put it back, even though it might be days later.

Thanks all. I located mine but have not had a chance to try and clean it out. It doesn't look like any fluid has come out of it. However the dip stick tube sure does. I am hoping that the vent is just plugged. Have any of you added a tube to the vent? Was there a TSB on that?

Thanks again.

The great ghetto trans vent TSB. There's a lot here if you take the time to look. TSB's can be researched using the link found in the sticky from the solutions to common problems forum Technical Service Bulletin Look Up
Using it yielded the TSB in question

The vent lets air out as the fluid gets warm and expands. Lets air back in when it cools down when your car is shut off. If it is stuck shut, the expanding fluid pushes the dipstick out of it's home and spills some fluid down the tube. It is very simple in how it works. It is in the highest point of the tranny housing so only air can come out the vent. The dipstick tube ends under the fluid level so it cannot act as a 'vent'.

Thanks for the info. Does anyone know where I would get one of those 90 degree vents. I believe the one that is on there is straight up with a cap on it.

Thank You.
